Peel, Benedek and Crowe (1981) describe a branch pore model for use with carbon adsorption. 4 Ion exchange with chemical reaction in the resin An early attempt to describe the rate of ion exchange processes was made by T h o m a s (1944) with a reversible chemical reaction of second order. Although 38 Principles of Ion Exchange Technology not a realistic model, it demonstrates most of the observed characteristics of ion exchange systems (Hiester and Vermeulen, 1952; Gilliland and Baddour, 1953; Dranoff and Lapidus, 1958,1961; Helfferich, 1962a,b; Kelly, Allen and Kennedy, 1970).
Bounds may be placed on the mass transfer coefficient using the lower and higher values of self-diffusion coefficients, but predictions of performance or the shape of breakthrough curves (discussed below) will not be accurate. Unfortunately, computational effort for rigorous solution is formidable. A baseline value of the j factor is given for single particle isotopic exchange expressed in the same manner as Carberry, but with a slightly different coefficient. This j is then modified according to interaction effects.
The orthogonal collocation method is often used in solving the differential equations for fixed beds (Ferguson and Finlayson, 1972; Michelsen and Villadsen, 1972a,b; Finlayson, 1972a,b). Costa, Rodrigues and Loureiro (1986) and Evangelista and Berardino (1986) discuss numerical methods and list useful available computer software. The use of the stagewise model with lumped parameters offers advantages of easier solution, using standard digital simulation packages, with some loss of precision of simulation because of the inherent back-mixing within stages (Radcliffe, 1984).
